TTOHWE Y pinion 32, in turn, meshes with a gear wheel 34 secured toashaft 35 rotatably supported by the bracket 2O and by a bracket 36secured to the machine head 10. The shaft V35 is provided, intermediatetheV supporting brackets and 36, with an endless screw 37.

A rod 38, slidably and rotatably supported by the bracket 36 and by abracket 39 secured to the head 10, carries a pair ofspring pressed jaws40 which are held in position upon the rod 38 by sleeves41 and 42 fixedthereto adjacent one end thereof. The inner ends of the jaws 40 areprovided with recesses shaped to conform to the endless screw 37 andprovided with threads to engage the Y threads thereof, wherebytheyjointly form a travelling nut, constituting a follower. As

theendless screw 37 is rotated, the'follower,

Y initsvsupporting brackets 36 and 39.

vformed of the inner ends of the jaws 40, will travel along vthe same,thereby causing a longitudinal movement of the rod 38 with- An actuatingmember 43 is adj ustably supported by the sleeve 4l, and is sopositioned that, when the rod 38 has moved a predetermined dist-ance, itwill engage the free'end .of an arm V44, operatively connected to thepulley 17, and actuate the arm, 44 to move the pulley 17 out ofengagement with the clutch member 19,. in order to disconnect the samefrom the driving shaft 16 of the electric motor 15.

A supporting memberV 45, fixed to the rod 38,- has removably securedthereto a guideplate, which servesv to support the hat-brim andto feedthe same to the needle 12, transversely to the normal line of feed. Asshown in Figs..1 to 5 inclusive, the guide-'plate consists of twosections 46 and 47, having their outer ends pivotally connected toy oneanother, as by a screw 48 engaging a block 49, AVand havingtheir innerends adjustably connected to one another by means of bolts 50, 50carried by the sections 46 and 47 and engaging aslotted, arc-shaped link51. The sections 46 47 of the guide-plate vare provided at theirV outeredges with upwardlyextending walls 52 provided, throughout a 'portion'of their length, with inwardy-extending portions 53. A finger-piece 54,carried by the block 49 `and by a bracket 55 secured tothe rod 38, isprovided for adjusting the rod 38 relatively to the machine head 10 inorder to properly position the guide-,plate 46, 47 with respect to theneedle 12 at the beginning of the stitching operation.

The guide-plate 46, 47 above described, is Aadapted for use inconnection with the stitching of hat-brirns of the tubular type shown inFig. 7. For stitching hat-brims of the flat, annular type, shown in Fig.8, an arcshaped guide-plate 56 is employed having upwardly-extendingwalls 57 at its outer edges, as shown in Fig. 6.r

When either` one of theguide-plates is in use, its inner end rests uponthe bed plate of the machine head 10 in front of the needle 12, thusinsuring that the hat-brim to be stitched will beproperly presented tothe needle 12, and the side walls of the guide plates prevent lateralshifting of the hatbrim. When the guide plate 46, 47 is used thesections thereof are so adjusted relatively to one another that thedistance between the inner ends of the walls 52, 52wi1l correspond tothe width of the hat-brim to be stitched.

The operation of the machine is as follows :V-V j i The guide plate 46,47 or the guide plate 56, is affixed to the supporting member 45,depending on whether the hat-brim to be stitched is of the tubular,r orfiat, annular type, and the rod 38 is moved to the left, as seen in Fig.1, in order to position the guideplate in advance of the needle l2.lVhen moving the rod 38 to thus adjust the guide jaws 40 will be openedto disengage them from the endless screw 37, by pressing upon the freeouter ends thereof When the guide plate is thus adjusted the hat-brim tobe stitched is placed in position upon the guideplate and upon the bedplate of rthe machine head 10. The arm 44 is then moved to cause thepulleyr17 toengage the clutch member 19 on the motor shaft 16, whereuponrotation of the shaft 13 will be effected. The rotation of the shaft 13will operate the needle bar 11, carrying the needle 12, in the usualmanner, and will also cause the rotation of the endless screw 37 on theshaft 35 by means of the gearing` above described. As

the endless screw 37 rotates it will cause the guide plate 46, 47,vor'56, as the case may be, to travel at a uniform rate from the left tothe'right, as seen in Fig. 1 in'a direction transverse to the normalline of feed of the machine Yand lat a slower'sp'eed than thatof thenormal feed, thus 'causing the stitching to be produced upon the ma- Yterial in a spiral form. i

At the completion' of the stitching Voperation the actuating member 43will engage the free end ofthe arm 44 and move the same to throw thepulley 17 out of engage-V ment with the clutch member 19, whereupon theoperation of the machine is stopped.

The distance between the adjacent rows of stitching on the hat-brim maybe varied by varying therate ofrotation of the endless screw 37, whichcontrols the transverse movement of the guide plate.r The rate of.`

rotation of the endless screw 37 may be altered by varying theproportion of certain of the gears and pinons, for example, by removingthe gear wheel 27 and pinion 30,

plate, itis of course understood that the or either thereof, andsubstitutingin place.

thereof a gear wheel and a pinion having a greater or a less'number ofteeth. The thus substituted gear wheel and pinion may be readilyadjusted to mesh with one another and with the remainder of the train ofgearing by varying the positions of the adjustably mounted arms 22 and24 relatively to one another and to the support 21, and by adjustablydisposed upon said slotted mem-y varying the position of one or both ofthe studs 26 and 33, upon which the gear wheels and pinions are mounted,within the slots 23 and 2.5 of the arms 22 and 24.

Having thus described my said invention what I claim and desire tosecure by Letters Patent is:

l. The combination of a sewing machine with a support to receive theVarticle to be stitched and a'rotatable member operatively connected tosaid support for moving the same transversely to the normal line of feedci the machine, a driven gear on said rotatable member, a driving gearfor transmitting movement to said driven gear, an intermediate gearbetween said driving gear and said driven gear, a supporting bracket forsaid intermediate gear, a pair of slotted members carried by saidbracket and a stud` adjustably secured upon said slotted members,substantially as specified.

2. The combination of a sewing machine with a support to receive thearticle to bc stitched and a screw-threaded member operatively connectedto said support for moving the same transversely to the normal line ofieed or" the machine, a driven gear on said screw-threaded member, adriving gear for transmitting movement to said driven gear, asupporting` bracket, a slotted member pivotally mounted upon saidsupporting bracket, a second slotted member associated with saidfirst-named slotted member, a stud bers, and an intermediate gearmounted on said stud for transmitting movement from said driving gear tothe gear on said screwtihieaded member, substantially as speci- 3. Thecombination of a sewing machine with a support to receive the article tobe stitched and a screw-threaded member operatively connected to saidsupport for moving the same transversely to the normal line of feed ofthe machine, a driven gear on said screw-threaded member, a driving gearfor transmitting movement to said driven gear, a supporting bracket, aslotted member pivotally mounted upon said supporting bracket, a secondslotted member associated with said first-named slotted member, a studVa plurality of sections adjustablyconnected to one another at theirouter ends and having means adjacent their inner ends to hold them totheir adjusted positions, and means tor moving said platetransversely tothe normal line of feed of the machine, substantially as specilied;
